Questions

How do I convert AAC to AIFF?

Drop your AAC file on this page, or choose it. Anyfile converts it on your device in a moment and the AIFF downloads straight away. To change it first, open it in the audio editor.

Is my AAC file uploaded anywhere?

No. The file is read and converted by your own browser, and nothing is sent to a server. You can check: open your browser’s developer tools, go to Network, and convert a file. No upload appears.

Can I convert several AAC files at once?

Yes. Drop them together and you get one ZIP with every AIFF inside.
